However, it can cause a significant drop in blood pressure (hypotension), especially in high-risk older patients with multiple medical conditions. This complication can lead to serious consequences such as heart attack, stroke, or death in vulnerable patients.\n\nThis study investigates whether keeping patients in a lateral (side-lying) position for 15 minutes after spinal anesthesia - instead of immediately turning them onto their back (supine position) - can reduce the risk of hypotension. When a patient lies on their side after receiving spinal anesthesia with a heavy (hyperbaric) local anesthetic, the medication tends to stay concentrated on the lower (operative) side, resulting in a more limited nerve block. This may help preserve blood pressure stability.\n\nWe will enroll 70 patients aged 65 years or older with high anesthetic risk (ASA physical status III or IV) scheduled for unilateral lower extremity orthopedic surgery under spinal anesthesia. Patients will be randomly assigned to two groups: one group will be kept in the lateral decubitus position (operative side down) for 15 minutes before being turned supine, and the other group will be turned supine immediately after spinal anesthesia. Blood pressure, heart rate, and oxygen saturation will be monitored continuously. The primary outcome is the incidence of hypotension during the first 15 minutes after spinal anesthesia.",[26,27,28,29],"Hypotension Drug-Induced","Spinal Aneshtesia","Geriatric","Orthopedic Surgery Patients",[31,32,33,34,35,36,37,38,39],"hypotension","spinal anesthesia","lateral decubitus position","geriatric","hyperbaric bupivacaine","unilateral spinal block","hemodynamic stability","orthopedic surgery","ASA III-IV","NOT_YET_RECRUITING","2026-05-12",{"date":43,"type":44},"2026-05-19","ACTUAL",{"date":46,"type":20},"2026-06-01",{"date":48,"type":20},"2026-08-10",{"name":50,"class":51},"University of Health Sciences Balikesir Hospital Eduation and Research","OTHER_GOV",{"id":53,"slug":54,"hasResults":11,"nctId":55,"briefTitle":56,"officialTitle":57,"acronym":4,"eligibilityCriteria":58,"healthyVolunteers":11,"sex":16,"minAge":59,"maxAge":4,"enrollmentInfo":60,"targetDuration":4,"studyType":21,"phases":62,"briefSummary":63,"conditions":64,"keywords":67,"overallStatus":78,"whyStopped":4,"lastUpdateSubmitDate":79,"lastUpdatePostDateStruct":80,"startDateStruct":82,"completionDateStruct":84,"leadSponsor":86,"locationsCount":89},"100592612","ketamine-for-preventing-post-spinal-hypotension-in-orthopedic-surgery-100592612","NCT06995690","Ketamine for Preventing Post-Spinal Hypotension in Orthopedic Surgery","Impact of Sub-anesthetic Dose of Ketamine in the Prevention of Post Spinal Hypotension in Patients Undergoing Orthopedic Surgeries","Inclusion Criteria:\n\n* Patients American Society of Anesthesiologists Physical Status (ASA) I to II undergoing orthopedic surgeries under spinal anesthesia.\n* Both Sexes.\n* Patients aged equal to or above 18 years.\n* Body mass index \\\u003C35 kg\u002Fm2\n* Duration of operation from 1 hour to 3 hours\n\nExclusion Criteria:\n\n* Patients' refusal of procedure or participation in the study.\n* Patients with contraindication to spinal anesthesia.\n* Patients with cardiovascular or pulmonary disease.\n* Patients with pre-procedural hypotension (systolic arterial pressure less than 90 mmHg and\u002For mean arterial pressure less than 60 mmHg).\n* Patients aged below 18 years.\n* Duration of operation below 1 hour or above 3 hours.","18 Years",{"count":61,"type":20},30,[23],"This randomized, double-blind, controlled clinical trial investigates the efficacy of a sub-anesthetic dose of ketamine (0.5 mg\u002Fkg IV) in preventing post-spinal hypotension in patients undergoing elective orthopedic surgeries under spinal anesthesia.

Risk factors for AKI include impaired renal perfusion, decreased functional renal reserve, as well as advanced age, peripheral arterial disease, diabetes mellitus, renovascular disease and congestive heart failure.
